Design and Analysis of Charge-Transfer Amplifiers for Low-Power Analog-to-Digital Converter Applications
<p>The demand for low-power A/D conversion techniques has motivated the exploration of charge-transfer amplifiers (CTAs) to construct efficient, precise voltage comparators. Despite notable advantages over classical, continuous-time architectures, little is understood about the dynamic behavior of …

Exploring the use of a higher octane gasoline for the U.S. light-duty vehicle fleet
… in octane number. Engine modeling simulations in GT-Power are used to determine the relative brake efficiency gain (part-load) that is possible for a unit increase in compression ratio. This is found to be 1.9% while literature data suggests a 2.33%-2.8% efficiency gain may in fact be possible. …
